SERGEY

Sergey is pygame-based slideshow
software. It is developed on GNU/Linux -- it may work on other
systems where pygame works, but I have no confirmation of that as of
now (email me if you've got it working, especially if you have
changes).

Features

full-height view of panoramic shots via scrolling (zooms to the left side, pans along panorama and zooms out upon reaching right side)

zoom in or zoom out of high-resolution shots

titles (intertitles or captions)

music with titles

Python-based "interface"

If you're not comfortable with a little bit of Python, this might not
be the program for you (yet) -- there's no GUI; you build a slideshow
as a Python list. If this appeals, there's an quick example slideshow
which downloads pictures from my Flickr account.
